Subject: [PATCH v3 6/6] riscv: dts: spacemit: Add CTF2301 on K3 CoM260
Date: Wed, 05 Aug 2026 02:00:56 -0700	[thread overview]
Message-ID: <20260805-ctl2301-v3-6-b86c75d1c552@linux.dev> (raw)
In-Reply-To: <20260805-ctl2301-v3-0-fd4b8ffb5b0d@linux.dev>

Enable I2C6 on the K3 CoM260 module and describe the Sensylink
CTF2301 temperature sensor and fan controller at address 0x4c.

Set the I2C6 pin power source in the board-level pinctrl node
because the IO rail voltage is board-specific.
